The silicon magnesium calcium fertilizer material of kind of different process implements the silicon magnesium calcium of identical equivalent, and seedling is carried out after 30 days according to varying environment CMC model
Detection high, in tests below group, tomato rice shoot purchasing site, initial height of seedling be with physiological situation it is consistent, and using with
Sample is taken in machine sampling, is tested as follows in experiment greenhouse：
1. using the silicon magnesium calcium granulated fertilizer of secondary granulation production, grant on tomato rice shoot surrounding soil, control normal light
According to, moisture, cultivate 30 days, this test group is A1, and height of seedling detection is carried out after 30 days；
2. using a silicon magnesium calcium granulated fertilizer for granulation production, grant on tomato rice shoot surrounding soil, control normal light
According to, moisture, cultivate 30 days, this test group is A2, and height of seedling detection is carried out after 30 days；
3. using the silicon magnesium calcium granulated fertilizer of secondary granulation production, grant on tomato rice shoot surrounding soil, control normal light
According to, Used in Rainy Seasons of Southern Cities is simulated, it is overcast and rainy（Precipitation was controlled at 10mm/ days）, cultivate 30 days continuous overcast and rainy 2 days events of stochastic simulation and be total to
7 times, this test group is B1, and height of seedling detection is carried out after 30 days；
4. using a silicon magnesium calcium granulated fertilizer for granulation production, grant on tomato rice shoot surrounding soil, control normal light
According to, Used in Rainy Seasons of Southern Cities is simulated, it is overcast and rainy（Precipitation was controlled at 10mm/ days）, cultivate 30 days continuous overcast and rainy 2 days events of stochastic simulation and be total to
7 times, this test group is B2, and height of seedling detection is carried out after 30 days；Testing result such as table 1.
5. using the silicon magnesium calcium granulated fertilizer of secondary granulation production, grant on tomato rice shoot surrounding soil, control is normal
Illumination, simulate Used in Rainy Seasons of Southern Cities, it is overcast and rainy（Precipitation was controlled at 10mm/ days）, the lasting continuous wet weather of simulation totally 20 days, this experiment
Group is determined to carry out calcium, magnesium, the measure of silicone content and urea content in C1,30 days;
6. using a silicon magnesium calcium granulated fertilizer for granulation production, grant on tomato rice shoot surrounding soil, control normal light
According to, Used in Rainy Seasons of Southern Cities is simulated, it is overcast and rainy（Precipitation was controlled at 10mm/ days）, lasting to simulate continuous wet weather totally 20 days, this test group is
Calcium, magnesium, the measure of silicone content and urea content is carried out in C2,30 days to determine.
The plant strain growth contrast in the case of different weather of the silicon magnesium calcium fertilizer of 1 technique of table and prior art
| Test group | Initial height of seedling/cm | Cultivated days/day | Final height of seedling/cm | Growth conditions |
| A1 | 5 | 30 | 20.3 | Well |
| A2 | 5 | 30 | 21.2 | Well |
| B1 | 5 | 30 | 19.6 | Well |
| B2 | 5 | 30 | 14.3 | Difference |
Data above analysis understands：A1 groups understand with the contrast of A2 groups:The secondary granulating process of the present invention and prior art are once pelletized
The silicon magnesium calcium fertilizer of technique productions, can meet the demand of plant growth, and prior art silicon magnesium calcium fertilizer, the release of silicon magnesium calcium compared with
Good, there was no significant difference with silicon magnesium calcium fertilizer of the invention for plant growth；B1 groups understand with the contrast of B2 groups:Of the invention and existing skill
The silicon magnesium calcium fertilizer of art, it is continuous it is overcast and rainy in the case of, the silicon magnesium calcium fertilizer of this technique, plant growth situation difference is little；Existing skill
The silicon magnesium calcium fertilizer of art, plant growth is suppressed；
Therefore, situation of the silicon magnesium calcium fertilizer for granulating process production of secondary granulating process of the invention and prior art in fine day
Under, can be good at meeting the demand of plant growth；Specifically the silicon magnesium calcium fertilizer of secondary granulating process production of the invention, has
There is preferable slow release effect, be prevented from continuous overcast and rainy causing silicon magnesium calcium to be largely lost in.
In order to more intuitively represent the process advantage of secondary granulating process of the invention, spy is with secondary granulation work of the invention
Under overcast and rainy environmental condition, the release of silicon magnesium calcium is dense in soil for silicon magnesium calcium fertilizer for granulating process production of skill and prior art
Degree is contrasted, and the silicon magnesium calcium fertilizer material of two of which different process implements the silicon magnesium calcium of identical equivalent, according to《NY/T
2272-2012 soil conditioner calcium, magnesium, the measure of silicone content》Measure on calcium, magnesium, silicone content in soil is respectively to contrast
Group tomato rice shoot Soil Surrounding is sampled, and after abandoning topsoil, takes difference deep soil 500g, dries, and drying is laggard
Row detection, obtains the concentrations versus of the present invention and silicon magnesium calcium fertilizer silicon magnesium calcium burst size in soil of prior art, such as accompanying drawing 1.
Data above analysis understands：Initial silicon magnesium calcium content is about 2.0 g/kg in soil, is used when using this technique
After the silicon magnesium calcium fertilizer of secondary granulation production uses the silicon magnesium calcium fertilizer once pelletized with prior art, in 1-2 days after fertilising
Maximum burst size can be reached, it is 5.9g/kg that wherein this technique uses the maximum burst size of the silicon magnesium calcium fertilizer of secondary granulation production,
It is 8.0g/kg that prior art uses the maximum burst size of the silicon magnesium calcium fertilizer once pelletized；
By it is continuous it is overcast and rainy after, the silicon magnesium calcium fertilizer of prior art it is continuous it is overcast and rainy in, silicon magnesium calcium content is quickly reduced, finally
The initial value of 2.0 g/kg is reduced to, but the silicon magnesium calcium content of 2.0 g/kg can not maintain the demand of plant growth；This work
The silicon magnesium calcium fertilizer of skill production it is continuous it is overcast and rainy in, silicon magnesium calcium content can be maintained at the scope of the stabilization of 5.0 more than g/kg,
So as to meet the demand of plant growth.
In sum：The present invention disclosure satisfy that the demand of plant growth, and this work using the silicon magnesium calcium fertilizer of secondary granulation
Skill has notable sexual clorminance using the silicon magnesium calcium fertilizer of secondary granulation production relative to the slow release effect of the silicon magnesium calcium fertilizer of prior art,
Therefore, present invention employs the technique pelletized twice, multiple auxiliary materials are employed and is wrapped up, ensure that the fertility of magnesium calcium fertilizer material
On the premise of normal release, strengthen magnesium calcium fertilizer material slow release, discharge steady the invention provides a kind of fertility persistence relatively strong, fertility
Fixed and nitrogen content silicon magnesium calcium fertilizer material higher, solves the problems, such as that fertility persistence is poor and nitrogen content is relatively low well.
